This is a list of the tallest buildings in the United Kingdom. As of July 2013 there are 57 habitable buildings in the United Kingdom at least 100 metres (330 ft) tall - with 45 of these in London, four in Manchester, two each in Birmingham and Leeds, and one each in Liverpool, Sheffield, Swansea and Brighton. If all under-construction and approved buildings are actually built, this figure will nearly double to 110. The Shard (formerly known as Shard London Bridge), in Southwark, London, is currently the tallest completed building in both the United Kingdom and the European Union; it was topped out at a height of 310 metres (1,020 ft) in March 2012, inaugurated in July 2012 and opened to the public in February 2013.

The United Kingdom has not been noted historically for its abundance of skyscrapers, with the taller structures throughout the country tending to be cathedrals and church spires. Despite this, since the mid-20th century the number of high-rise apartment buildings and office blocks in most large British cities has grown significantly. In recent years there has been a boom in the number of skyscrapers proposed and approved for construction in the United Kingdom, particularly in London.
